PCV stands for Positive Crankcase Ventilation. If you did that, you wouldn't ventilate the crankcase. All those impurities/gasses would just stay in there and build up pressure..............not a good thing.

There is definitely a pressure relief even when re-routed.

I rerouted mine and i even have some oil that passed though the hose (through a filter) and onto my framerail.

I couldnt imagine the seal damage you could do plugging it up

A friend of mine put a new chrome breather on his camaro forgot to cut out the bottom of the grommet, revved the motor up and blew out the oil pan gasket. No ventalation so the pressure had to escape somewhere.

OUCH!!

That makes sense. Thanks!! Oh and what are the benefits of doing this again?

no oil buildup in turbo or intake.

If you are getting oil from your PCV then there is a problem. You should not be getting enough blow-by to worry about. I have 18,500K on mine and I use rottela T and use no oil and I live in the mountains, no mods, is there a coralasion between mods and blow-by. Just a thought!

No matter what your going to get oil in your intercooler if you dont reroute. Every truck does it.

There is definitly oil down there, not sure what could be causing it? A crazy tune? I generally am good to it, and it shows no signs of problems or other leaks...

Its enough oil for me to worry about it going through the turbo, but not enough to prove problems after re-route :)

This is how I did my PVC rerout. I only used one hose to the frame.

Just a thought!Look at your intercooler conections, If you dont see any wetness around the conections than pull a tube off and look inside, you will find that it is wet.

I change my oil every 3- 4.5K and maybe lose about an 1/8 cup of oil through that filter.

If your losing enough oil through a re-route to turn on your oil light, then yes, i agree there is a problem!:eek:

Tony good post with the pros and cons especially the cons , know what you mean about the leaky cummins i cringe evertime my buddy parks in my driveway.:eek:

Since I rerouted mine and I cleaned the engine bay-- my engine stays a lot cleaner-- no more blown oil fumes.:D

A brandy spankin new engine will collect oil in the PCV system. Its just the nature of the way an engine opperates. some of the oil vaporizes, there is nothing that can be done about that. It then condenses in other areas. So there will always be some oil that collects in the PCV system, no matter what. If there is a substantial amount, say a half quart or more a day then yes, there is a problem. but if you're loosing 1/8th of a cup in 5K miles there is no problem.

Is there any reason to reverse the by-pass back to stock when taking the truck in for service?

Depends on your dealer!

Nice filter, where did you get it?

I got the filter at my local speed shop. You can order the filter form Summit or Jegs. It is just a filter with a 1/2 tube.

thanks,

I am either going with that style filter or one of those catch containers that a lot of guys use. I have some el cheapo mickey moused filter on there right now so i could run the truck, oil is all over my frame rail on the drivers side.

If you have Tony's kit, hose diameter is 5/8" Here is one from Summit Racing.

I installed the reroute and the hose kink while I was driving, Smoked blue like it was a gasser with bad rings. I guess the exsessive pressure creates a blow by forcing oil into the combustion camber. umkink hose problem solved.
Hate to see what my egr looks like after 164000 miles? Blocked hope its not to late.

I took it one step further after the std. copper elbow and heater hose reroute.

Since I deleted the cat I fabricated an exhaust evac. system like on my hotrod.

Used an air pump check valve off a 73 chevy truck, fabricated a tube from a 5" long 1/2" dia. black pipe from home depot which mimic'd the moroso ones. It then got welded into the mbrp straight pipe. I had to use some copper tubing and elbows which I soldered together to get it to come up next to the firewall. I wanted to be able to change the check valve every so often thru the fender well so I had to snake it up and around the floor pan.

Noe that, my friend, is genius. Thanks for passing that along! :Handshake

What is the advantage to doing this?

:nopics:

How about some pics? Please!

It keeps a light positive suction on the pcv system like the turbo does.
theres pics in my garage of the entire set up. I had to massage the floor pan a little, but Ill own this truck for ever so I dont mind

I was reading the DIY section and noticed everyone reroutes both sides down below to the atmosphere. Why not just connect the 2 pipes together? Less tubbing, no oil drips to worry about, etc... Why not just put a plug on each side and get rid of the tubing altogether?

Anything wrong with not venting?

thanks...


Definatly don't plug it. I saw a cummins isx that had a pinched blow by tube and it took out the turbo oil seals and then the valve cover gasket. And for anyone rerouting the pcv hoses make sure theres nowhere in the hose that moisture can collect. It can freeze during the winter and plug it up. Ive never seen it on a pickup but ive seen it on newer Freightliner Columbias.

Pull the pcv valve off the mouthpice,put a brass elbow in it and run 1 hose wherever you want. Cap the port on the mouthpiece. Easy, cheap, and it works.

Use a 3/4 X 1/2 copper elbow from the "Big Box" plumbing section! Also an added benefit, your engine compartment will stay so much cleaner! :cool:
